KU mathematics student identifies flaw in published research article

This past spring semester, Nathan Betts '16 was searching the web for articles dealing with the assignment problem for his senior seminar project.  He found the article "A New Approach of Solving Single Objective Unbalanced Assignment Problem" by Yadaiah and Haragopal published in the peer-reviewed American Journal of Operations Research (AJOR), 2016, 6, 81-89.   He was suspicious of the approach discussed in the paper and brought it to the attention of his operations research professor, Dr. Fran Vasko.  Together they studied the approach and Dr. Vasko confirmed Nathan's suspicions that the approach did not guarantee the optimal solution to the assignment problem (as claimed by the authors).  Nathan Betts and Dr. Vasko wrote a rebuttal paper proving by counter example that the proposed method in the paper by Yadaiah and Haragopal does not guarantee the optimal solution to the assignment problem. 

The paper by Mr. Betts and Dr. Vasko entitled "Solving the Unbalanced Assignment Problem: Simpler is Better" was recently published in the AJOR, 2016, 6, pp. 296-299 (click here to read it!).  Due to the circumstances surrounding the paper, the editor waived the open access fee for the Betts and Vasko paper.

Congratulations to Mathematics major Danielle Sienko for her receipt of a copper Chambliss Student Academic Achievement Award in the categories of successfully completed research projects and outstanding service to the Kutztown University community. She has developed a solution procedure that can easily be used to assign class times to final exam time slots such that the number of students that are scheduled for three exams in one day is minimized. She has been able to show that using this mathematical approach reduces the number of students with three final exams scheduled in the same day by about 50%. 

Due to her continued work with the registrar's office, her approach will be implemented in Fall 2016.

Kutztown University's Department of Mathematics was recently highlighted for its cutting-edge work in applied mathematics at the 8th International Congress on Industrial and Applied Mathematics (ICIAM), August 10 - 14, 2015, in Beijing, China. KU was one of only nine institutions in the world to be recognized. 

ICIAM is organized by the International Council for Industrial and Applied Mathematics, the umbrella organization of professional applied mathematics societies world-wide, including the Society for Industrial and Applied Mathematics.

KU's Department of Mathematics' applied mathematics research was highlighted in a six minute video that was broadcast at the conference. The video focuses on the 2002 seminal paper on the Cable-Trench Problem (CTP), which was authored by Dr. Francis Vasko, Dr. Ken Stott, Mr. Rob Barbieri, Dr. Brian Rieksts and Mr. Ken Reitmeyer. Stott was a Bethlehem Steel researcher (now retired). The other three co-authors are Kutztown University graduates. Extensions and applications of this CTP work have been published world-wide in research journals. 

The video includes interviews with faculty members Dr. Francis Vasko, Dr. Eric Landquist, Dr. Yun Lu, Dr. Paul Ach; recent computer science graduate, Mr. Ken Zyma; Kutztown University President, Dr. Kenneth Hawkinson; and Acting Provost, Dr. Anne Zayaitz.

In the video, Landquist discusses recently published work with Vasko on extensions of the CTP that have applicability to improving medical imaging. Zyma discusses his Master's thesis research in which he uses the CTP to find a cheaper cabling network to connect an array of radio telescopes for inclusion into LOFAR, the world's largest connected radio telescope. 

Members of the Kutztown University applied mathematics faculty are also very involved in the development of new solution approaches for solving complex combinatorial optimization problems that have many real-world applications. In the video, Lu discusses the need for metaheuristics as key solution strategies for these very difficult problems.


AUGUST 10-14, 2015

KU mathematics professor Dr. Yun (Amy) Lu attended the 8th International Congress on Industrial and Applied Mathematics (ICIAM 2015) in Beijing, China. She gave two invited talks that were based on joint work with Dr. Fran Vasko, KU mathematics professor, and Kenneth Zyma, a former KU graduate student in the Department of Computer Science. Furthermore, Kutztown University's Department of Mathematics was one of only nine institutions world-wide to be highlighted for its cutting-edge work in applied mathematics at this conference. The Department of Mathematics' applied mathematics research was highlighted in a six-minute video that was broadcast at ICIAM 2015; to watch it, scroll up to the next entry on this page!

APRIL 10-11, 2015

On Friday, April 10 and Saturday, April 11, the Kutztown University Department of Mathematics hosted the 2015 PASSHE Mathematics Association (PASSHE-MA) conference. More than 70 participants from 19 institutions gathered to discuss mathematics and mathematics education. There were more than 40 faculty and student talks over the two days, including seven Kutztown students and ten Kutztown professors who presented their research.

This conference was highlighted by two plenary talks. The first, on Friday evening, was by Dr. Neil Sloane, President of the On-Line Encyclopedia of Integer Sequences (OEIS) Foundation. The OEIS is a free website ( that contains information about a quarter of a million sequences, and is often called one of the most well-known and useful mathematical sites on the internet. The second plenary talk, on Saturday afternoon, was by Dr. Jenna Van Sickle from Fontbonne University. Dr. Van Sickle told us about incorporating student-led learning into courses; she explained how this can engage and inspire students, as well as improve the classroom culture.

The Kutztown Department of Mathematics dedicated this conference to Professor Randy S. Schaeffer, who passed away unexpectedly on October 22, 2014. He was a distinguished member of Kutztown University, a valued colleague, educator, mentor and friend who will never be forgotten.

The PASSHE-MA conference is held annually, rotating among the PASSHE universities. It was last held at Kutztown in 2002.

It is with profound sadness that we announce the passing of Professor Randy Schaeffer '72.



It is with great pride that we announce that Jesse Bailey, Zach Moran, and Ian Tomes have won the 6th annual Cumberland Valley Math Modeling Challenge held at Shippensburg University! This prize is awarded based on the presentation of their problem and solution as judged by the other competitors. Their problem was to determine a rating system that identifies the best U.S. city in which to live for people in the 18-35 age range, 36-64 age range and the 65+ age range. They had 24 hours to develop a model, write a two-page summary of their solution and propose a presentation of their solution. They have agreed to present their solution at the October 14 Math Club meeting. Come check it out. Congratulations!

OR Insight: 25 articles from 25 years

To celebrate the 25th anniversary of the journal OR Insight, its editors have reviewed the papers published over the last three decades and have made a selection of 25. These reflect both the way the application of OR has developed over the years and the different areas which have benefited from its application. OR in action has always found a home in OR Insight.

Although all 25 articles are interesting, you might want to consider article #21 by Dr. Vasko and Dr. Ache, Department of Mathematics, and Natalie Snow, Institutional Research. The link is
